摘要
陆路交通发展对湘西地区经济联系具有重要意义。通过可达性测度模型和区域经济联系量测度模型,定量分析了湘西地区1949—2017年长时间序列下,陆路可达性以及经济联系的时空演变特征。研究发现:①区域陆路可达性空间格局逐渐由交通廊道扩展型,演变为不规则环状结构扩展型,总体呈现“核心—边缘”的结构特征。②各城市对外经济联系总量均有大幅度的增长,非均衡化发展趋势与地域分异特征明显。③区域经济联系显著增强,逐渐形成以怀化市、张家界市、武冈市为中心的多核心经济联系格局,组团结构明显,组团之间联系疏散,区域经济一体化程度较低。④区域首位经济联系呈现组团式空间形态,首位经济联系中心城市的变化表现出一定的由水运影响向陆路影响的转变。鉴于此,湘西地区应加快构建布局合理、结构完善的陆路交通网络体系;加强中心城市及有潜力城市的发展与建设;重视水陆交通综合体系发展规划,依托内河水运振兴滨水城市,构建合理多元化发展的区域经济联系格局。
The development of land transportation is of great significance to the economic contact in Xiangxi area.By the accessibility measurement model and regional economic tie measurement model,the temporal and spatial evolution characteristics of land transportation accessibility and economic contact from 1949 to 2017 in Xiangxi area are quantitatively analyzed.It is found that:1)The spatial pattern of regional land transportation accessibility has gradually evolved from the traffic corridor expansion to the irregular ring expansion and shows a"core-edge"pattern as a whole;2)All cities have increased greatly of their external economic contact volume,and the imbalanced development trends among different regions are obvious;3)Regional economic contact have been significantly strengthened,which has led to a multi-core economic pattern centered around Huaihua,Zhangjiajie and Wugang,combined structures are obvious,while their connections are not that close,and the regional economic integration is at a low level;4)Regional priority economic contact represents a combined spatial structure,and the changes of regional priority economic contact core cities are influenced from water transportation to land transportation.In view of these,the construction of land transportation network system with reasonable layout and perfect structure should be speeded up;the construction of central cities and potential cities should be strengthened;the development planning of land and water transportation comprehensive system should be paid more attention,coastal cities should be revitalized through inland waterway transportation,and a rational and diversified regional economic contact pattern should be built.
